It’s rewarding because every day you come in to work you don’t quite know what’s going to happen. It’s quite exciting in that sense – it’s unpredictable

Prince William

The green jumpsuit apart, this could be any worker in any office in the country.

But it’s Prince William at work, giving us a glimpse into his life in an intimate series of pictures which reveal his day-to-day job.

Gone are the tailored suits and formal attire. Instead Flight Lieutenant Wales, 30, is in a practical work suit, with his hair slightly dishevelled.

And instead of an army of flunkies to serve up lavish feasts and the finest wines, down-to-earth Wills is happy to make his own brew and drink it out of his favourite mug.

The Duke of Cambridge – just voted favourite royal – is also snapped making his own bed in a plain bunkroom, with no special treatment given or expected by Wills.

In another photo, a relaxed William jokes with colleagues. But his work is no laughing matter.

As a helicopter search-and-rescue pilot on Anglesey, he is responsible for saving lives when people get into danger.

And while the Prince might admit to enjoy playing Call Of Duty during his downtime, he can never be more than 60 seconds away from his aircraft at RAF Valley.

His royal status counts for nothing as he works 24-hour shifts like everyone else. During his spell on duty, he beds down in his bunkroom, leaving wife Kate, 30, alone at the couple’s rented farmhouse.

William says: “It’s rewarding because every day you come in to work you don’t quite know what’s going to happen. It’s quite exciting in that sense – it’s unpredictable.

“But at the same time, it’s great that you get to go out and actually save someone’s life hopefully or at least make a difference to somebody.”

The Prince, second in line to the throne, starts each day with an 8am briefing from the outgoing rescue team.

After the update on the weather and other local details, his four-man crew must be in the air within 15 minutes of a call for help.

At 10pm they switch from Readiness State 15 to Readiness State 45, meaning they have 45 minutes to prepare for night-time casualties.

The Search and Rescue force attend about 1,950 call-outs a year, many of them in north Wales which is popular with walkers and climbers.

The shots show Wills honing his skills with extra training to prepare him for rescues on land, sea, mountains and in flooded towns.

He is also seen checking his aircraft – a Sea King Mark 3, which can carry 17 passengers and fly for up to six hours.

Towards the end of his shift William prepares a comprehensive brief for the next day’s crew, then fills them in on what lies ahead, before hanging up his flying kit and heading home.

But once he has clocked off, he remains on “second standby” for most of the next day, in case he is needed to support more complex search-and-rescue operations.

The Prince adds: “When you know that they are in trouble, you do everything you can to get there.

“The skills the guys employ to survive the weather and whatever sort of situation you are thrown into – it’s definitely advanced flying and it’s rewarding, so put the two together and it’s a fantastic job.
